Peace, it's the only thing the Avatar world needed and finally they received it. The final battle against the tyrant Firelord Ozai ended in the avatar's favor. Aang and the others, however, couldn't do it without the help of Sonic The Hedgehog. Strange that he ended up in their dimension, but sonic planned to go there. He helped them to take down the Firelord, even when he did it himself. So now the war is over, sadly Sonic had to leave his new friends to return back to his dimension. The world celebrated with great joy. The gang are glad that their mission is completed, but sometimes things aren't always as they seem.

A war, it's ended. The avatar and friends are returning to the Southern Water Tribe. Its been so long since the water benders chose to come to the southern water tribe to rebuild it. Now the gang are flying on Appa toward the newly rebuilt tribe. "I can't wait to see the tribe now that Master Pakku came to rebuild it.'' katara spoke up "I just want to land and get something to eat.'' Sokka whined "Guys! I think we're here!'' Aang announced. Katara and Sokka looked in the distance and saw the that the tribe got larger. There was a more spread out circular wall around the tribe with watch towers and walkways of ice made along the top of the wall.

Aang steered Appa down into the tribe. Katara and Sokka put their parkas on to keep them warm. "Wow I can't believe it! Its beautiful!'' katara shouted in joy. Toph hopped of the saddle, "One of you better guide me around so I can sit and rest, I'm tired.'' she said. "It's great to see you.'' a voice came. Katara and Sokka turned and saw their father, Hakoda. The two siblings rushed to him and embraced. They separated, "I'm glad to see you two alright.'' said Hakoda. "Aang how are you?'' Hakoda asked "Alright, just glad to have some peace and quiet.'' Aang smiled "That's great, now let me show me you where you will be staying.'' he told them. Sokka had to have Toph follow him so she wouldn't get lost. When Hakoda showed them to their hut, which was built on the outside with snow and ice. In the inside were furs, pelts and a fire pit in the middle to keep the inside warm. "I wonder what we're gonna' do now that the war is over?'' said Toph laying on a hammock "I never thought of it enough, but no need to worry about it.'' Aang responded "I wonder if we'll be able to see Sonic again.'' katara said like it was out of the blue. "Wouldn't you wonder too?'' she said sitting up "He had to go back to his dimension or whatever he calls it." Sokka said laying down. Without anymore talking, the gang went to sleep, but later they'll have one very rude awakening.

It was in the morning when the gang woke up. But they heard loud noises such as bangs, rumbling, almost sounded like something was coming their way. Then an earthshaking rumble woke the four heroes up. They got dressed quickly, they saw people running all over the place. Sokka headed toward the wall of the tribe. He saw in the distance three Fire Nation ships coming their way. "Aang you might wanna come see this!'' Sokka shouted out. Aang and the others made their way to the wall and gazed at the incoming fire nation ships.

"No way! How?'' aang exclaimed. "It doesn't matter now, we have to defend the tribe.'' Sokka announced. The ships launched fireballs upon the tribe, people took cover from the bombardment. The ships arrived at the walls of the tribe. The lowering bridge broke through the walls. "Sokka take Toph somewhere safe!'' aang yelled out. Sokka guided Toph to the back of the village to safety. Firebenders and warriors rushed out of the ships. "We're highly outnumbered.'' katara said "No your not.'' said Hakoda running to their side, along with him were water tribe warriors and benders. Aang smiled, then looked back to the enemies before them. Both sides then charged at each other. Swords and spears clashed, fire benders shot flames at a group of warriors, aang shot a gust of wind in its path to stop the flames. The battle was chaotic. Katara ducked from a fireball then shot a blanket of snow upon the fire benders. "This isn't going well!'' hakoda shouted knocking out a fire nation warrior. Aang launched a medium sized tornado at a large group of fire nation troops flinging them all over the place. "Fall back!'' Hakoda shouted "What!?'' aang exclaimed "We have to! We'll corner them further in the village.'' he told him. Aang agreed, katara and the other water tribe troops retreated further back into the village, hoping that they could hold out.

Afar from the carnage in the tribe, on a lone glacier a blue portal started to open up. Flying out of it was a gold flash, it was heading toward the southern water tribe. The gold light crashed into the back of one of the fire nation ships making a hole that made the metal bend inwards. However the fire nation didn't see it. The mysterious figure was no longer glowing gold, just a dark silhouette. He backed up against a wall and looked around the corner down the hall.

A Firebender was on his way down the hall, the figure hid back behind the wall. Once he saw the fire bender he pushed him against the metal wall and punched him in the chest knocking the wind out of him leaving his body to collapse to the floor. The figure walked into a room, he saw a fire nation cloak. He grabbed it and put it on, put the hood over his head and marched out of the room to find the exit out of the ship.

Aang stepped out of cover to fire a gust of wind out of his staff at the fire nation troops then quickly went back behind cover from fire being shot at him. "How long can we handle this?'' Aang exclaimed "Just keep fighting.'' Hakoda answered. Katara rose a ice wall to hold off the fire benders. The three got out of cover. "That should hold them.'' katara said. Waterbenders ambushed from the left and right of the fire benders. "Finally we're pushing them back.'' aang smiled. Then breaking through the ice wall was a fire nation tank. "RUN!!'' aang yelled. Katara and Hakoda ran separate to get away from it. Aang opened his glider and flew over it. Aang looked at the top of the lowering bridge, there stood Azula.

Aang ran into a hut and found Katara and Sokka with Toph inside, hiding. "Why are you here hiding? Shouldn't you be fighting?'' Aang questioned "We can't risk ourselves and die out there!'' Sokka shouted back "Do you know Azula is leading this attack?" Aang asked "Oh.'' Sokka said. "We have to go to separate spots of the village and defend them.'' Aang told them. Katara and Sokka agreed and followed Aang outside. From the first ship at the lowering bridge the figure in the cloak watched the fighting going on in the tribe. He saw katara running to the right side of the tribe, but waiting there were three fire benders and a fire nation tank. He took action and jumped from where he stood to Katara's position.

Katara turned around the corner and gasped, staying where she stood. The three fire benders got in fighting stances with the tank following them from behind. Katara backed up into a dead end. "Stand down Waterbender.'' one of the fire benders said. Katara shot five icicles toward them, he burned them with fire before reaching him. He then fired a flame at her leg, hitting her and making a serious burn. She fell to the ground and watched the fire benders come closer. "Anything left to say?'' the fire bender said. Katara saw a figure jumping over them. He kicked one in the side of the head, then struck another in the stomach.

He grabbed the last one and threw him to the side. The tank attempted to run the person over, but he did a short back flip on the top of the tank. He drove his fist into the hatch, he ripped it off and jumped inside. The fire benders inside were thrown around and beat up. The figure destroyed the engine and leaped out of the opening in the top of the tank leaving it to explode. Katara started to heal her leg and continuously looked from her leg to heal it and the figure marching at her. Aang blew back a group of fire nation troops until he spotted Katara's dilemma.

Aang fired a strong gust of wind at the figure into a ice house, making a hole inside the house. Aang rushed to her side and helped her up. Aang brought her into a hut. "Stay here.'' he told her and ran out of the hut. Katara gritted her teeth from the wound that remained on her leg. Katara walked outside despite of what aang told her. She looked down the path and saw three fire nation spearmen. They charged at her, then once again the cloaked figure came and grabbed one of their spears and beat him over the head with the other end of it. The figure dodged to the left from one spearmen lunging at him with the weapon, he grabbed the spear and threw him into the air eventually he landed back onto the ground.

He turned to the last one and gave him a glare, the spearmen ran away cowardly. Katara stood still as the mysterious savior walk toward her. "Who are you?'' she asked. Problem is he was short, she had to look down. From behind them, Azula spotted them. An evil smirk crept on her face. She fired a fireball. The figure heard it coming. He pulled katara down to the ground and stood in front of her with his arms shielding his face. The fire hit him, a smoke cloud raised. The smoke started to die down, katara had her eyes shut then looked to see the cloak was burned off. The so called mysterious savior was Sonic The Hedgehog. He looked at her out of the corner of his eye with a smile and said: "I'm back.''
